UNITED STATES JOHN D. WAGNER, OF CHICAGO, ILLINOIS.

WINDOW-SCREEN BRACE.

Application filed. February 19, 1923. Serial No. 619,784.

To all whom it may concern:

Be it known that I, JOHN O. asman, a citizen of the United States, and a resident of the city of Chicago, in the county of (look and State of Illinois, have invented certain new and useful Improvements in I'Vindow- Screen Braces; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the numerals of reference marked thereon, which form a part of this specification.

This invention relates to a brace for window screens.

It is an object of this invent-ion to providean expansible brace which can be readily applied to screens of varying width, and which can be readily constructed and assembled.

With these and other objects in view which will become more apparent in the following description and disclosures, this invention comprises the novel mechanisms and combination of parts hereinafter described and more particularly pointed out in the appended claim.

In the accompanying drawings which il lustrate a preferred embodiment of this invention and in which similar reference numerals refer to similar features in the different views:

Figure 1 is an elevational view of a window containing a screen braced transversely according to my invention.

Figure '2 is an enlarged fragmentary and broken elevational view of a screen with the brace secured thereto.

Figure 3 is an enlarged transverse section of the screen showing the brace in plan view.

Figure a is an enlarged fragmentary and longitudinal section through the screen showing the brace in section.

Figure 5 is an enlarged elevational view of the brace per se.

In the drawing there is shown a screen comprising the frame 1 in which the forami nous sheet 2 is secured in a well known manner. In the present instance, the screen is illustrated as comparatively long to fit a long narrow wind-ow. Such a screen needs to be transversely braced, and the problem of this in mechanism that is adapted to be manufactured in standard sizes and later fitted to screens of varying width.

This aforementioned mechanism comprises the lugs 3 having inwardly extending arms 3; each arm being provided with a scoket or guideway which in the present instance is formed by rearwardly extending parallel flanges 3, the ends 3 of which are bent toward each other as shown in Figure 5. These lugs 3 are stamped so as to fit the irregular surface of the frame 1, and they are provided with spaced apertures to receive securing bolts for fastening the same to the frame 1. A transverse bracing bar f preferably of channel cross section for lightness is supported in the sockets of a pair of lugs; the construction being such that the sockets exercise a frictional clamping action upon the bar It is readily apparent that the bar 4 may be cut to any length if it happens to be too long to fit the width of the screen.

In applying a brace to a screen, the transverse bar f is assembled with respect to a pair of lugs 3. The lugs are then properly adjusted as by contracting or spreading them apart and bolting upon opposite sides of the frame as shown in Figures 1 and 2. It will, of course, be understood that the bar 4 has previously been cut to the desired length to fit the screen, if it was not originally cut the proper length.

It will be observed that the bar 4; need not be of exact length since it is frictionally clamped and retained by the sockets in the arms 3) and as these lugs can be adjusted longitudinally with respect to the bar 4, so as to bring them closer together or to spread them further apart, the brace may be contracted or expanded to fit varying widths of screens. It is, however, preferable to construct the bar a so that its ends may abut the inner edges of the frame.

I am aware that numerous details of construction may be varied through a wide range without departing from the principles of this invention, and I therefore do not purpose limiting the patent granted, otherwise than necessitated by the prior art.

I claim as my invention:

An expansible brace for a window screen comprising a transverse channel shaped bar and a pair of lugs conforming to the screen beam and secured thereto and having inwardly extending directed arms providing sockets for frictionally engaging said bar.

In testimony whereof I have hereunto subscribed my name. i

J OHN O. WAGNER.
